So my week one favorite Jaleel went, literally, flat on week two. And that presents a perfect opportunity to speechify more about ballroom technique! Specifically, the footwork of jive. Maybe I should have discussed that when I was preaching about jive vs. Lindy Hop last season. But then there would have been no need for this cogent explication, now would there.
Lindy Hop is danced flat (hence everyone wearing sneakers or saddle shoes). Jive, as one of the Latin dances, is danced almost entirely on the balls of the feet (and both partners wear heels - heels automatically pitch you onto the ball of the foot). That allows the dancer to get a lot of spring in their step - literally. So if someone is using the whole foot, they are really not able to create any bounce through the foot. Or (let me qualify that) they have to work really hard to create any bounce through the foot. And the more difficult something is to execute, the less likely it is to be executed.
The kicking & flicking done in jive is created through the body - tucking the midsection to draw up the knee; the up & down action is all done with the feet. You land on the ball of the foot, squeeze the heel down to the floor, and then immediately are back onto the ball of the foot. This is why competitions always run jive as the last dance in the International Latin division, because right after doing a full-power jive, even very fit competition dancers are ready to STOP.
